In this work, the effect of annealing temperature and Cr3+ concentration on the structural and optical properties of the SnO2 host crystals has been investigated. The Cr-doped SnO2 samples were synthesized by a simple hydrolysis method, using SnCl4.5H2O as the host precursor and CrCl3.6H2O as the source of dopant.

Ebook "Organotrifluoroborate preparation, coupling and hydrolysis" reports on the reactivity of organotrifluoroborates, which are becoming increasingly important reagents in synthesis. The thesis is divided into three sections. The first section describes a method for preparing organotrifluoroborates. The second section reports on a mechanistic investigation into the main application of RBF3K reagents as coupling partners in Suzuki-Miyaura coupling, phenomena identified as arising from organotrifluoroborate hydrolysis and fluoride release.

Processing methods affect starch hydrolysis, digestibility, absorption and glycaemic index (GI) of food. Although some studies have reported on the effect of boiling, frying, roasting and baking on glycaemic index of traditional staples, there is limited information on the contribution of drying, fermentation, boiling and steaming on starch bioavailability and glycaemic index.

In this work, an enzymatic liquid-gated field-effect-transistor sensor based on chemically reduced graphene oxide film was developed for determination of acetylthiocholine in aqueous conditions. The device was designed with interdigitated electrode configuration and then manufactured by combining lithography and chemical vapor deposition techniques in clean room.

The synthesis of natural products 2-(2,3-dibromo-4,5-dihydroxyphenyl)acetic acid (1) and 2-(2,6-dibromo-3,5- dihydroxyphenyl)acetic acid (2) and as well as their derivatives 25 and 26 were carried out by substitution, hydrolysis and demethylation reactions of the corresponding four benzyl bromides. The antioxidant potentials of benzylic acid-derived bromophenols were, for the first time, appraised by several outstanding bioanalytical methods.

Spent coffee ground (SCG) has attracted increasing attention since it contains many useful components such as polysaccharides, protein, lipid, and bioactive compounds. The aim of this research was to enhance the enzymatic hydrolysis to release important sugars in the SCG using different pretreatment methods. Spent coffee grounds were pretreated by alkali pretreatment, organosolv pretreatment, and the combined process

Regenerating jute into high-tech nanofibres is an alternative way to use jute fibres. However, dissolving jute has always been a challenge. The complex hierarchal structure of lignin is the main obstacle for hydrolysis of lignocellulosic fibres in obtaining value-added products. This work aims to develop regenerated jute nanofibres through electrospinning. A literature review was conducted to investigate on the methods of regenerating jute for value added products.

For the first time the synthesis of poly(N -vinyl-2-pyrrolidone)-stabilized cobalt-palladium nanoparticles by an easy method, their characterization, and their use as active catalysts for hydrogen release from hydrolysis of ammonia borane and hydrazine borane is reported here. The catalyst is prepared by simultaneous reduction of suitable cobalt and palladium ions by sodium borohydride in the presence of poly(N -vinyl-2-pyrrolidone) as a stabilizer. They are characterized by UV-Vis spectroscopy, TEM analysis, X-ray diffraction, and X-ray photoelectron spectroscopy.

We reported a facile one-pot synthesis of bimetallic CoCu nanoparticles (NPs) anchored on graphene hydrogel (GH-CoCu) as catalysts in hydrogen generation from the hydrolysis of ammonia borane (HAB). The presented novel one-pot method composed of the reduction of the mixture of graphene oxide, cobalt(II), and copper(II) acetate tetrahydrates by aqueous ethylene glycol solution in a teflon-coated stainless-steel reactor at 180 °C. The structure of the yielded GH-CoCu nanocatalysts was characterized by TEM, SEM, XRD, XPS, and ICP-MS.

ZnO:Ni powders are prepared by forced hydrolysis method. The samples were investigated by using XRD, SEM and photoluminescence (PL) spectra. The intensity of near band gap photoluminescence as a function of doping concentration and temperature was studied. The researching results show the doping concentration of Ni strongly affected the luminescence in the UV spectral region and reveal application potential of ZnO:Ni material in optoelectronic and magneto-optical devices of UV range.

The presented work is devoted to the development of synthesis methods for novel 2-[(3-aminoalkyl-(alkaryl-, aryl-))-1H -1,2,4-triazolo]anilines. Abovementioned compounds were obtained via hydrazinolysis (Ing-Manske procedure) and acid hydrolysis of corresponding N -acylated{([1,2,4]triazolo[1,5- c ]quinazolin-2-yl)alkyl-(alkaryl-, aryl-)}amines. The regioselectivity of hydrazinolysis and hydrolysis were established. The features of spectral characteristics were studied and discussed.

This study investigated extracted OS structures derived from three different rice bran AX using Ultraflo Max. Rice bran AX extracted from commercially defatted rice bran (COM) yielded the greatest OS amount (83.39 mg/g RBAX), followed by that of the Sanpahtawng cultivar (27.05 mg/g RBAX), and lastly, the Chainat1 cultivar (21.53 mg/g RBAX), as evidenced via Ultraflo Max enzyme hydrolysis. Interestingly, A3X was the primary OS product in all rice bran AX hydrolysates prepared by Ultraflo Max.

High performance liquid chromatography was applied for the determination of tryptophan in food. The sample was hydrolyzed in a duration from 16 to 24 hour by protease enzyme at 50o C. The extract was separated on the C8 reversed phase column with mobile phase of NaH2PO4 50mM pH 2.3: Methanol (82:18; v/v). The linearity of the method was kept in the range of 0.5 - 50 mg/L. Limit of detection was found to be 4.6 mg/100g.
